Hi,

Just wondering if anyone has upgraded the ROMs for a TFTC and what the CPU and Display upgrades actually do.

Thanks!

Mine are updated - I haven't noticed any particular differences whatsoever. I just prefer to have up-to-date roms as long as they don't dampen the functionality of the machine (XF for instance, newer roms = magnets don't work as often causing the filing cabinet to get pummeled by the pinballs).

Updated ROMs change the Door video mode. Older roms have a predictable pattern. New ROMs are totally random.

Was wondering if it may fix a slight dmd glitch. All lines work, just in some instances when the dmd uses darker text/numbers it's not fully visible.

Any suggestions?

the later roms have random placement if points in Door Prize mode. The earlier ones have a set pattern.

Your glitch sounds more like out gassing. If that's the case it's time for a new dmd. Post a picture of your dmd when it looks like this.

The random door prizes is the only change I noticed when I upgraded a few months back.

It seems fine for the most part but it fades when displaying the darker text. (See photos)

Time for a new dmd me thinks.

I'll look to see if mine does the same thing, and report back.

Whoa - yeah - your DMD is starting to bite it D: ... that looks like the early signs of out-gassing:

Taken from the Repairing DataEast Pinball Guide:

"Outgassed" Score Displays.

Score display glass has a limited life; it does not last forever. Time will eventually kill these, and the display will "outgas" and fail. Because of the high voltage involved with score displays, the anode and/or cathode inside the display glass breaks down. This results in the "outgassing" of impurities that eventually change the internal gas properties, so the display can't glow (the gas must be very pure for the display to work). There is no fix for this other than replacing the display glass (which has become fairly expensive now). Outgassing affects dot matrix displays very often, but it also applies to alpha-numeric displays too (see the alpha-numeric section below for more details).

An outgassed score display puts much higher electrical loads on the power supply. When a display starts to outgas, it should be replaced immediately! Otherwise, the repair may involve fixing a damaged (burnt) power supply, in addition to replacing the score display glass. "

The part that makes me wonder is the fact that there isn't a section that is always blacked out. It lights up with most text, and doesn't with the darker less bright text. Strange.
